ok diz iz my 300ZX ... so im worried cuz whenevah it start it or drive it ya can smell da gas . is dat mean i have a gas leak somewhere or do i have an exhaust leak ?

 

Could be either ..... most of the time it would be an exhuast leak... but never can tell with an older car... best bet it to get up under your car and check it out.

 

thanx

 

Had the same problem and looked under the hood and found that a clamp for my fuel reg came a little loose... Let the car run for a couple of minutes with the hood up and it will hit you hard with the smell.. You might have to open the throttle from under the hood so the gas can have some more pressure.. Good luck.
